1996 Other Land Rover Models V8 Four Wheel Drive Automatic 160.00 miles
I have changed the cat, coil, ht leads, and plugs.
When starting is firing on all after driving for a while will suddenly misfire then after a while will clear it's self then run fine for about 10 miles then the same thing happens.
Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
